SDK Platform-Specific Usage Notes Prompt Template

This prompt is for SDK engineers and developer relations teams who need to adapt generic API documentation into idiomatic, platform-specific guidance. The core job is translating a single API concept—such as a method, a data model, or an authentication flow—into concrete, compilable usage notes for a specific language or runtime. The ideal user already has access to the canonical API reference and understands the target platform's conventions. They are not writing the reference from scratch; they are bridging the gap between a language-agnostic contract and the threading models, memory management patterns, package managers, and async idioms that a platform developer actually uses.

Use this prompt when you have a stable API surface and need to produce consistent, high-quality platform notes across multiple SDKs. It works best for statically typed, compiled languages where conventions are strict (Java, Swift, Kotlin, Rust) and for dynamic languages where idiomatic patterns vary widely (Python, JavaScript, Ruby). Do not use this prompt to generate the underlying API reference, to invent platform behavior that isn't in the source code, or to document experimental APIs that are still in flux. The prompt assumes the target platform's idioms are well-understood; if your team hasn't standardized on patterns for error handling, async execution, or resource lifecycle, resolve that first.

Before running this prompt, gather the canonical API specification, the target platform's style guide, and at least one reviewed example of a similar usage note from your existing documentation. The prompt includes placeholders for [API_SURFACE], [TARGET_PLATFORM], [PLATFORM_CONVENTIONS], and [EXAMPLE_NOTES]—fill these with concrete, sourced material. After generation, validate that every code example compiles against the current SDK version and that all platform-specific claims (thread safety guarantees, memory ownership, nullability) match the actual implementation. For high-risk surfaces like authentication or payment methods, add a human review step and require evidence grounding against the source code.

This prompt template is designed to take a generic API method description and adapt it into idiomatic, platform-specific usage notes for a target language or framework. It forces the model to consider threading models, async patterns, memory management, package managers, and platform constraints before producing documentation. The output is structured so it can be directly embedded into an SDK reference page or reviewed by a platform expert.

You are an expert SDK documentation engineer specializing in [TARGET_LANGUAGE] and [TARGET_FRAMEWORK].

Your task is to convert the following generic API method description into platform-specific usage notes for [TARGET_LANGUAGE] developers.

## GENERIC API METHOD DESCRIPTION
[METHOD_NAME]
[METHOD_SIGNATURE]
[METHOD_DESCRIPTION]
[PARAMETERS]
[RETURN_TYPE]
[ERROR_CONDITIONS]

## PLATFORM CONTEXT
- Language: [TARGET_LANGUAGE]
- Framework: [TARGET_FRAMEWORK]
- Package Manager: [PACKAGE_MANAGER]
- Async Model: [ASYNC_MODEL]
- Threading Model: [THREADING_MODEL]
- Memory Management: [MEMORY_MANAGEMENT]

## OUTPUT REQUIREMENTS
Produce a usage notes section with the following structure. Use [TARGET_LANGUAGE] code blocks for all examples.

### 1. Import and Setup
Show the exact import statement and any required client initialization specific to [TARGET_LANGUAGE].

### 2. Method Signature in [TARGET_LANGUAGE]
Show the idiomatic method signature as it appears in the SDK, including async keywords, callbacks, or reactive types as appropriate.

### 3. Parameter Mapping
Map each generic parameter to its [TARGET_LANGUAGE] equivalent. Note any type differences, default values, or builder patterns.

### 4. Basic Usage Example
Provide a complete, runnable example showing the method call with realistic values. Include error handling that follows [TARGET_LANGUAGE] conventions.

### 5. Async and Threading Notes
Explain how this method behaves under [ASYNC_MODEL] and [THREADING_MODEL]. Note any blocking calls, coroutine requirements, or thread-safety guarantees.

### 6. Memory and Resource Management
Describe any resource cleanup requirements, disposable patterns, or memory considerations specific to [MEMORY_MANAGEMENT].

### 7. Error Handling
Map each generic error condition to its [TARGET_LANGUAGE] exception type or error handling pattern. Show a try-catch or equivalent example.

### 8. Platform-Specific Constraints
Note any [TARGET_LANGUAGE]-specific limitations, such as platform availability, version requirements, or known incompatibilities.

## CONSTRAINTS
- All code examples must compile under [SDK_VERSION] with [PACKAGE_MANAGER].
- Do not invent parameters or behaviors not present in the generic API description.
- If a generic concept has no direct [TARGET_LANGUAGE] equivalent, explain the idiomatic alternative.
- Flag any security considerations relevant to [TARGET_LANGUAGE] (e.g., credential storage, TLS configuration).
- Mark any sections that require human verification with [REVIEW NEEDED].

To adapt this template, replace each square-bracket placeholder with concrete values before sending it to the model. The [TARGET_LANGUAGE] and [TARGET_FRAMEWORK] placeholders control the entire idiomatic surface of the output. The [ASYNC_MODEL], [THREADING_MODEL], and [MEMORY_MANAGEMENT] fields should be filled with specific terms like "coroutines with async/await," "Grand Central Dispatch," or "garbage-collected with try-with-resources" rather than vague descriptions. The [SDK_VERSION] constraint is critical for validation: if the model generates code that uses APIs not available in that version, the output fails. After generation, run the code examples through a compiler or linter for the target language to catch syntax errors before publication.

This prompt is designed to sit inside a documentation generation pipeline, not as a one-off chat interaction. The typical harness receives a source API reference document (the generic, language-agnostic spec) and a target platform identifier (e.g., python, java, node, swift). The harness injects both into the prompt template along with a structured output schema that defines the required sections: threading model, async patterns, memory management, package manager instructions, platform constraints, and idiomatic code examples. The model must return valid JSON matching that schema so downstream tooling can render it into a documentation page or diff it against an existing page.

Validation should happen in two layers. First, a schema validator checks that the JSON output conforms to the expected structure, that all required sections are present, and that code blocks are non-empty strings. Second, a language-specific validator runs the generated code examples through a compiler or linter for the target platform (e.g., mypy for Python type stubs, javac for Java snippets, tsc for TypeScript). If either validation layer fails, the harness should retry the prompt once with the validation error appended as feedback in a [CORRECTION_CONTEXT] placeholder. After two failures, the output is flagged for human review rather than retried indefinitely. This prevents the pipeline from silently publishing broken code examples.

For production use, log every invocation with the prompt version, model identifier, target platform, validation pass/fail status, and retry count. This trace data lets you identify which platforms or API surfaces produce the most failures and where the prompt template needs improvement. If the documentation covers authentication flows, credential handling, or security-sensitive patterns, always route the final output through a human review step before publication—no exceptions. The model can draft platform-specific guidance for OAuth token storage or certificate pinning, but a security engineer must confirm that the guidance doesn't introduce vulnerabilities. Wire the human review gate into your CI pipeline so that unreviewed security content blocks the documentation deploy.
